Abstract
A method for local heating includes placing first magnetic material in a first lumen, and a second magnetic material in a second lumen from the first magnetic material to a magnetically permeable rod, then applying alternating magnetic fields. The first lumen may be a fallopian tube. A method of occluding fallopian tubes uses a catheter to inject first magnetic material into the tubes, injecting second magnetic fluid into uterus, introducing a magnetically-permeable rod into vagina, positioning a second end of the rod over the fallopian tube and applying an alternating magnetic field to the first magnetic material to heat it. The method is performed with apparatus having a coil wound over a magnetically-permeable rod, a high frequency AC generator coupled to the coil, a first magnetic fluid capable of generating heat in an alternating magnetic field, and a second magnetically-permeable magnetic fluid capable of conducting magnetic fields through a lumen.
